[Rpm-maint] [rpm-software-management/rpm] Parametric macro arguments are not expanded (#127)

[Panu Matilainen]

```
%define mymacro() \
echo foo\
echo bar
```
...is the line-continuation syntax.

As for the rest, it depends on what you need to do with it. If the arguments are always non-%{nil} then there's nothing you need to do. If arguments can be %{nil} (or otherwise empty), then you have two choices:

1) escape the argument in the *caller*, eg "%sdkbindir %%{nil}". If you need to pass unexpanded macros through several layers of macros as seems to be the case, then you need to escape them at each caller. So in the sdkbindir() case, you'd use %%{1} in the calls to %sdkdir.
2) handle the "missing" argument in the parametric macro (ie callee, instead of caller, basically), by using ?-conditionals.
